Hoffman served his sentence at
Millhaven Institution maximum security prison. In 1980, for an appeal of the guilty verdict, Hoffman hired
Brian Greenspan, the younger brother of the famous lawyer
Eddie Greenspan, to serve as his defense counsel. Greenspan in turn was able to obtain the records of the telephone calls made from the Kitchener clubhouse, which the police had bugged. The police records showed that Hoffman had made three phone calls from the Kitchener clubhouse on 18 October with the last one starting at 8:40 and ending at 8:45 pm. In the last phone call to a biker named Joe Ertel, the latter stated that he would soon be joining Hoffman in replacing the lock, which supported Hoffman's statement that he was not in Port Hope at the time of the murder. The phone records made by Sauvé showed he had called the Toronto clubhouse twice on 18 October 1978, but had placed no calls to the Kitchener clubhouse. Meinhardt noted that the Crown's theory was that Sauvé was the mastermind of the murder plot and called the Toronto clubhouse to ask the bikers to come with him to the Queen's Hotel to kill Matiyek. Greenspan noted that the Crown's theory was that Sauvé had also phoned Hoffman to take part in the same murder, but there was no evidence that Sauvé contacted Hoffman at all prior to the murder. On 13 April 1982, the Ontario Court of Appeals ruled for another trial for Hoffman was needed due to the new evidence discovered by Greenspan. Hoffman was acquitted of the murder, but found guilty of being an accessory after the fact. On 21 March 1983, Justice Gregory Evans sentenced Hoffman to four years in prison for being an accessory after the fact for Matiyek's murder. The fact that Hoffman was not in the Queen's Hotel at the time of the murder makes his murder conviction a very controversial one. Hoffman did not complain about his prison sentence and did not seek to turn Crown's evidence won him much respect within Satan's Choice. That the police had these intercepts of Hoffman's phone calls on 18 October 1978 all long, which were not disclosed by the Crown to the defense as per the rules regarding evidence disclosure, was controversial and the American journalist
Mick Lowe feels that Hoffmann should never have been charged with Matiyek's murder, let alone convicted. After serving his sentence, Hoffman resumed his career at B.F. Gooderich, married, and had two daughters. On 29 December 2000, Satan's Choice joined the
Hells Angels. Hoffman was unwilling to join the Hells Angels and instead retired as a member in "good standing". In 2001, Hoffman's wife died of cancer, leaving him to raise his two daughters alone. He told Lowe that when his eldest daughter entered
Wilfrid Laurier University in September 2012, it was one of the proudest moments of his life. Hoffman became active in weightlifting and served as the president of the Ontario Powerlifting Association, where he sought to combat steroid abuse in weightlifting. In 2013, the Canadian journalist Paul Dalby called Hoffman's conviction "a real travesty" of justice. Lowe said of Hoffman's conviction: “But they [the police] never disclosed it [the phone records] and they allowed this man to be convicted of a murder he did not commit and had nothing at all to do with. There is no argument about that. We know that for a fact.” ==Books==
